According to Blabbermouth.net,  SEPULTURA members Derrick Green (vocals) and Andreas Kisser (guitar) joined KORN on stage last night (Saturday, October 19) to perform SEPULTURA‘s classic song “Roots Blooody Roots”. Professionally filmed video footage of their appearance can be seen below (Note: Skip to around 47-minute mark.) Green wrote on Facebook afterwards: “What a cool surprise tonight rocking out ‘Roots Bloody Roots’ with KORN!! Too much fun!!”
